Rugged Quick Visual Reference of Angle


A Clinometer (or Inclinometer) is an instrument for measuring angles of slope (or tilt), elevation or inclination of an object with respect to gravity. Also known as a slope or tilt meter, angle indicator, gradiometer, and pitch or roll indicator.

Rieker manufacturers clinometers using precision tube and ball construction. All our tubes are filled with a special damping fluid that controls the movement of the ball and will operate in temperatures from -50 F to +180 F (-45C to +82C). Our industry leading quality and control standards provides for the smoothest and most consistent roll among any other clinometer of this type world wide.

The housing is made of a rugged 100% Polycarbonate, making these clinometers extremely tough for all types of environments and weather conditions. The large, clear number and degree markings make it easy to get quick, accurate readings - clearly readable from 12 feet away. In ranges of 5, 10, 26 and coming soon 45 there is a clinometer to fit most all needs.

Easy to install, these Rieker clinometers were originally designed for precise heel and trim indication on sailboats - one of the most popular in use today. However, a clinometer can be used where ever leveling, balancing and preventing tip-over is needed: such as utility trucks, aerial lift equipment, military and government vehicles.

If you have an application that requires custom specifications, please contact us today - one of our application experts will be happy to speak with you.
